The Sandberg Wireless Headset ANC FlexMic is an advanced wireless headset with a microphone that you can wear comfortably for hours thanks to its stylish ear cushions. The built-in ANC (Active Noise Cancellation) feature ensures excellent, undistorted sound, whether you are sitting in a noisy office or exposed to the constant noise of airplane or train engines. The detachable and flexible microphone boom allows you to capture sound optimally during online meetings, gaming, or IP telephony calls. The built-in microphone allows you to use your headphones discreetly, even when the microphone boom is not attached. The built-in battery can be easily and universally charged via a USB connection, and a single charge provides up to 13 hours of operation.
